¥-amean
1 TM: estimate mean of
factor A, level 1 and label it TM in the output dataset
¥-acontr
: specifies contrast matrix and
label in output dataset
1 1 1 1: all of factor A's levels summed = 0?-1 1 -1 1: contrast between human and tools (HM +
HP) Ð (TM + TP) 1 1 -1 -1:
contrast between motion and points (HM + TM) Ð (HP + TP) 0 1 0 -1: contrast between human motion and
points (HM Ð HP)É É ¥-fa
StimEffect: F-statistic
for main effect of factor A (any differences among stimuli?)
